j BEARING. y

To @ZZ whom it may concern.'

Be it known that I, HENRY Gr. HEIST, a citizen of the TJnited States, residing at Schenectady, in the county of'l Schenectady, State of New York, have invented certain new and useful Improvements in Bearings, of which the following is a specification.

My invention relates to bearings for ma chines provided with vertical shafts, and is particularly applicable to machines of large diameter.

The shaft of such a machine carries the rotatable member of the machine, and is supported by a thrust bearing, which is in turn supported b-y a bearing bracket in the form of a bridge structure mounted on the stationary member of the machine. Heretofore, such bridge structures have been so constructed that the thrust bearings had to be mounted above and on top of the bridge structures, thus requiring a very long shaft and a greater height of station for accommodating the eXtra tall machine.

In accordance with my invention, the bearing bracket is so constructed and arranged that the thrust bearing for supporting the rotatable part of the machine is located between beams forming the bridge structure and below the upper edge of the beams. By constructing the bearing bracket in this way, the shaft of the machine is considerably shortened, and at the same time, the beams forming the bridge structure may be made deeper and lighter than was heretofore possible.

For a better understanding of my invention reference may be had to the following description taken in connection with the accompanying drawing, in which Fig. 1 is a view partly in section of a machine embodying my invention; and Fig. 2 is a top view of the machine of Fig. 1.

In the drawing, I have illustrated my bearing in a dynamo electric machine having a stationary member 1 and a rotatable member 2 mounted on a vertical shaft 3. The dynamo electric machine shown in the draw* ing is of the alternating current type having a stationary armature and a revolving field and is driven by a motor (not shown) of any well known type, connected to the lower end of the shaft. My invention is not limited to dynamo 'electric machines, and may be used in any kind or type of machine in which the rotatable membervis mounted on a vertical shaft.

The vertical shaft 3 has a sleeve or guide bearing 4 and av thrust bearing 5, both of which may be of any wellknown type.; My new bearing bracket comprises a member 6 on which these bearings are mounted and a plurality of beams 7. The beams 7 are supportedl on the stationary memberwlloffthe machineand are spaced apart, as clearly shown `in Fig. 2 throughout their length.

-The member 6 is supportedl between the j beams 7 and between the upper and lower edges thereof, andv the ybearings 4 and 5 yare located between the upper rand lower edges of the beams 7.

The `member '6 is shown'as. comprising a deck 9 supported `between ribs 1'0`and somewhat below the middle thereof,l the'ribs 101 being supported by end plates 11 vwhich are 1 fastened to the beams 7 by means of bolts 12.

thrust bearing comprises relatively rotatablev plates 13 and 14. The plate 13 is relatively rigid and inflexible and rotates with the shaft 3. The plate 14 is in the form of a thin, flat, flexible ring of metal, and is supported on a large number of' helical springs 15 arranged close ltogether so that they7 may in effect constitute an elastic cushion under the plate 14.

The bearing bracket construction as described above is well adapted to be made of castings, structural steel or reinforced concrete, and makesl it practicable to build the beams 7 deeper and consequently lighter than it was possible to build the beams of bearing brackets as heretofore constructed. Furthermore, this construction allows the beams 7 to be placed far enough apart so that there is working room between them for removing the thrust bearing 5. It also Vpermits the use of a much shorter shaft for the machine than was possible heretofore.

What I claim as new and desire to secure by Letters Patent of the United States, 1s:

beams supported. on said stationary memberof said machine and spaced apart throughout their length, said-'member onwhich said thrust bearing is supported being supported fromsaid'beams and between the upper and lower edges of said beams,said thrust beai ing being located between the upper and lower edges of said beams.

2. In amachine having rotatable and stationary members and a `vertical shaft on which said'rota'table member is mounted, a

thrust bearing and a guide'bearing for said shaft, and a bearing bracket vfor, supporting said thrust-bearing and saidguide bearing 'comprising a member 'on which said thrust lbearingvand said guide bearing are mounted, `a plurality of separate beams supported on said stationary memberof said machine and vspaced apart throughout their length, said member on which said bearings are mounted being supported :from said :beams and between the upper and lowere'dges thereof,

said bearingsbeinglocated between the upper and lower edges of saidlbeams.

3. 4In a machine having rotatable and stationary members and a vertical Vshaft on which said rotatablefmember is mounted, a

- thrust bearing for said shaft, and a bearing bracket for supporting said thrust bearing comprising a member having a deck, said thrust bearing being mounted on said deck, a plurality ofbeams supported on said stationary member of said machine and spaced apart throughout their length, said member beams so that said deck is located between being supported from and between said the upper vand lower edges of said beams,

said thrust bearing being located between the upper and lower edges of said beams.

l.v In a machine having rotatable and stationary members and a rvertical shaft on which the rotatable member is mounted, a

kthrust bearing and a guide bearing for said shaft, and a bearing bracket for supporting said thrust'bearing and said guide bearing comprising a member having a deck, said thrust bearing being mounted on said deck,

said yguide bearing being mounted on said member below said deck, a plurality of :beams supported on said stationary member of said-niachine yand spaced apart through i out their length, said memberr being supported from and between said beams so that said deck is located between the uppeiaiid lower edges of `said beams, said bearings being located between the upper and lower edges ot said beams.

In ywitness whereof, I have hereunto set my hand this l28th day of February, 1922.
